Welcome to Janav’s page

I was introduced to programming because of a buring desire to make video games.

I was not able to make any video games because I was not very good at art. After speaking to other students at UCSD I found this meme to be very accurate.

This is how smart people solve memory leaks.

Here is a random quote I found on the internet

Opportunities don’t happen, you create them

I like interesting and clever solutions to problems. Here is some code in c++ to calculate the inverse of the square root of a number from the original Quake III arena video game (taken from here)

float Q_rsqrt( float number )
{
	long i;
	float x2, y;
	const float threehalfs = 1.5F;

	x2 = number * 0.5F;
	y  = number;
	i  = * ( long * ) &y;                       // evil floating point bit level hacking
	i  = 0x5f3759df - ( i >> 1 );               // what the fuck? 
	y  = * ( float * ) &i;
	y  = y * ( threehalfs - ( x2 * y * y ) );   // 1st iteration
//	y  = y * ( threehalfs - ( x2 * y * y ) );   // 2nd iteration, this can be removed

	return y;
}

This code was used in a game engine to approximate the inverse of a square root quickly. The code gives up some accuracy in favour of speed. More information on this code can be found in this video.
